Ok I replaced the Cps Sensor in my 96 powerstroke, the sensor is from o' reilly's, after I did so the truck runs rough. Did i get a bad sensor, and need to replace it with a motorcraft sensor. By the way it wasn't doing this before I replace the cps. Any help appreciated.

 

I would. Parts store sensors can be a crap shoot.

 

Motorcraft or International are always the safe choice
